why are my quads twisting as I scale them?

I’m trying to simplify my foliage creation process by having volume shapes of quads and scale them in place so they over lap in a “fluffy” way.

I have gotten them to stay in place, but for a reason when I scale them they have a twist apply to them which ruins the whole effect.

How would I go about fixing this?

IDK why my original images are broken, I added fixed images, but the old ones don’t appear in the edit, so I can’t remove them
